摘要：

To determine the lead soluble forms in laboratory rats tissues in exogenous intoxication experiment a procedure of phosphate buffer extraction (PBS) and electrothermal atomic-absorption determination has been proposed. The detection limit of the lead soluble forms is 0.03 mg/kg. The relative standard deviation in the samples with more than 0.1 mg/kg lead does not exceed 0.2.
